Description
技术领域:
本发明属于包装材料技术领域,具体涉及一种防渗透高强度复合瓦楞纸板。
背景技术:
瓦楞纸板始于18世纪末,19世纪初因其量轻而且价格便宜,用途广泛,制作简易,且能回收甚至重复利用,使它的应用有了显著的增长。到20世纪初,已获得为各种各样的商品制作包装而全面的普及、推广和应用。由于使用瓦楞纸板制成的包装容器对美化和保护内装商品有其独特的性能和优点,因此,在与多种包装材料的竞争中获得了极大的成功,成为迄今为止长用不衰并呈现迅猛发展的制作包装容器的主要材料之一。
瓦楞纸是由挂面纸和通过瓦楞棍加工而形成的波形的瓦楞纸粘合而成的板状物,可以有三层、四层、五层等结构。瓦楞纸板在使用中经常会遇到挤压等情况,瓦楞纸板受到挤压时,瓦楞纸板的耐破度对纸板的抗挤压性能有很大的影响,在受到超过瓦楞纸板的耐受压力时,就会发生明显的形变,影响瓦楞纸的使用。常规的产品中三层纸板强度低,使用过程中易发生形变,常规五层纸板强度略高于三层纸板,但是由于制造密实度不够,强度也不高,而且耗用成本高,占有空间和体积大。此外,瓦楞纸板在使用中还可能会被雨水、海水打湿,影响其使用,常规的三层纸板和五层纸板不具备防水、防潮的效果,一般在5分钟内全部渗透,施胶最好的也不超过10分钟,不能很好的保护包装物品。
发明内容:
本发明的目的在于针对现有技术中的不足,提供一种防水渗透的四层复合瓦楞纸板,通过使用特制的胶水配方,使得瓦楞纸具有优异的防水渗透性能。
为解决上述技术问题,本发明采用的技术方案为:一种防水渗透的四层复合瓦楞纸板,由面纸、里纸和两层芯纸制成,其创新点在于:所述的两层芯纸之间以及芯纸与里纸之间通过胶黏剂A粘合;所述的两层芯纸与面纸通过胶粘剂B粘合;所述的胶黏剂A和胶黏剂B均由水、玉米淀粉、烧碱、硼砂和丹宁混合而成。
进一步的,所述的胶黏剂A由如下重量份的成分组成:水950-1050份、玉米淀粉280-290份、烧碱8-12份、硼砂2-3份、丹宁55-58份。
进一步的,所述的胶黏剂A由如下重量份的成分组成:水1000份、玉米淀粉285份、烧碱9.8-10.2份、硼砂2.3-2.7份、丹宁56.8-57.2份。
进一步的,所述胶黏剂A的糊化温度为60℃。
进一步的,所述的胶黏剂B由如下重量份的成分组成:水750-850份、玉米淀粉280-290份、烧碱8-12份、硼砂2.5-3.5份、丹宁48-52份。
进一步的,所述的胶黏剂B由如下重量份的成分组成:水750-850份、玉米淀粉285份、烧碱9.8-10.2份、硼砂2.6-3.0份、丹宁49.8-50.2份。
进一步的,所述胶黏剂B的糊化温度为58-60℃。
本发明的有益效果:
1、提高强度:本发明的复合瓦楞纸,中间增加胶水层,瓦楞纸的环压强度明显加强,由原来的9.0环压指数升到了13以上,再加上集聚效应,总体承压强度增加了近50%,在同定量的情况下,其强度相比综合定量的五层纸板要高到5%~10%。
2、防水、防渗透:本发明的瓦楞纸板在90分钟内不渗透,最长15小时不渗透,对包装物品起到很好的防护效果。
具体实施方式:
下面结合具体实施例对本发明的技术方案作详细说明。
本发明的一种防水渗透的四层复合瓦楞纸板,由面纸、里纸和两层芯纸制成,两层芯纸与面纸通过胶粘剂A粘合;两层芯纸之间以及芯纸与里纸之间通过胶黏剂B粘合;胶黏剂A和胶黏剂B均由水、玉米淀粉、烧碱、硼砂和丹宁混合而成。
本发明的在胶水配方中加入丹宁,丹宁的分子式为C76H52O46,能够使淀粉中的蛋白质固化沉淀,其沉淀物不易渗解于水,不易渗解于水的纳米级细微颗粒填充与纸张纤维的间隙和表面,形成一层薄膜,有效隔断了水的传导,起到了防水、防潮的作用,当遇到雨水等潮湿的情况,瓦楞纸板的面纸受潮变湿,而纸板的反面却能够保持干燥,达到防水防潮的效果。
